Endou-kun no Kansatsu Nikki

A high school student named Tsuda finds himself seated behind Endou due to a change in seating. Their relationship begins with a minor occurrence, allowing Tsuda to observe Endou, whom he had never truly known before. He notices small details—Endou's mole, his slender nape, his soft hair, and the slight expressions he makes. As Tsuda, who typically remains indifferent and avoids deep connections, grows closer to Endou, he begins to feel uneasy about the lingering distance between them. He is left questioning the source of these emerging emotions.
